Patent EP-0478528-A1 (EP)
Inventor: TORREGROSSA LOUIS O
IPC: B01J19/00
Filed: 1991-08-14
Abstract: Organic constituents in a liquid, such as a waste water from a municipal or industrial process (e.g. bleach plant extraction liquor from the bleaching of paper pulp) may proceed effectively without the addition of alkali. When the organic constituents are reacted with an oxygen containing gas at appropriate pressure and temperature conditions, oxidized organics and gaseous acidic products of oxidation (e.g. CO₂) that are produced are continuously and immediately removed from the liquid so that they do not significantly contribute to lowering of the pH of the liquid, so that the reaction may proceed and the liquid remain alkaline. 
     This may be accomplished in a gas sparged hydrocyclone (40) in which the liquid is introduced into the first end (41) of a vortex (59) while oxygen is introduced from exteriorly of the vortex (at 49) into contact with the liquid, or may be accomplished by causing the liquid to flow in a thin film in a downwardly extending spiral path (19) and removing the acidic gases from a center portion (32) of the spiral path. A reactor (16) for effecting the last mentioned procedure includes a pressurized vertical vessel having a downwardly extending stationary spiral surface mounted in the vessel substantially concentric with it. Surface manifestations (29) may be provided on the spiral surface for enhancing mixing of liquid with surrounding gas (Figure 1).

Date Jun. 27, 1991.A surface wave reflection filter includes an input transducer, an output transducer, and a reflector in a first propagation track. To compensate for undesired surface waves proceeding directly between the input and output transducers, as opposed to the desired surface waves which are reflected before reaching the output transducer, a second propagation track is provided. The second track includes a input transducer and an output transducer, and is either connected in phase opposition to compensate for the undesired signal, or is constructed to generate a signal in phase opposition. A sump may be provided in the second track, a second reflector may be provided in the first track or in the second track, and the two tracks may be on separate or the same substrates.

Abstract: A lead frame comprising a lead frame base of a Cu alloy and an oxide layer formed thereon. The Cu alloy is the one which has dispersed particles, part of which distribute and is exposed on the surface of the alloy, or the one containing P of 30 ppm or less. In the case of the lead frame base made of the alloy containing the dispersed particles, since an oxide layer including oxides of the dispersed particles is formed, the adhesiveness of the oxide layer is improved. In the case of the lead frame base made of the Cu alloy including a specified amount of P, an oxide layer having an excellent adhesiveness can be formed too. By virtue of such oxide layers, the adhesiveness to a shielding resin is improved and the reliability of a semiconductor package can be improved.

Abstract: Des échantillons numériques d'un signal vidéo de système de télévision à haute définition sont comprimés au moyen d'un procédé qui consiste à déterminer des groupes de chacun de trois échantillons successifs dans les lignes de signaux vidéo, les groupes de lignes adjacentes étant décalées les unes par rapport aux autres, et à transmettre seulement un premier échantillon dans chaque groupe (par exemple B dans la ligne n). Chacun des second (P) et troisième (Q) échantillons dans chaque groupe est comparé avec les intensités de moyenne obtenues de trois échantillons initiaux adjacents transmis (A, B ou B, C), un échantillon provenant de chacune des lignes de signaux vidéo précédentes, simultanées et suivantes, afin de déterminer la correspondance la plus proche. Un code à 2 bits représentant cette correspondance est transmis pour chacun de ces second et troisième échantillons dans chaque groupe. Les groupes, et par conséquent les premiers échantillons, sont décalés les uns par rapport aux autres dans des lignes de signaux vidéo adjacentes, et la fréquence d'échantillonnage est de préférence un multiple impair de la moitié de la fréquence de lignes de signaux vidéo afin de décaler les pixels échantillonnés dans des lignes de signaux vidéo adjacentes. L'invention permet d'obtenir un taux de compression élevé, qui peut être augmenté par le codage à modulation différentielle impulsion-code des échantillons initiaux successifs.

Abstract: Method for the automatic coordination of an independent intersection traffic light control device with neighbouring intersections. The traffic flowing therefrom is recorded and analysed, where, for a predefinable measuring time period (MZ) with a number (I) of time intervals (ti), the number (Z) of vehicles per time interval is determined and stored. The measuring time period is divided up into test cycles (Zy) with equal-length cycle time (TZ). Within the test cycles, the number of vehicles is added up for each associated time interval. Such a mapping of the total measuring time period onto a test cycle enables mean value and variance formation for these numbers. Mappings and variance calculations of this type are carried out for further test cycles with respective different cycle times. Since the size of the variance provides a measure of the cyclic characteristic of the traffic flow, an existing vehicle cycle and its cycle time are determined from the calculated variances for the coordinated control of the traffic lights. <IMAGE>

Abstract: The fatigue resistance of lead-tin eutectic solder is increased by doping the solder with less than about 1.0 weight % of a dopant selected from cadmium, indium and antimony. The doped eutectic solder exhibits increased resistance to thermally or mechanically induced cyclic stress and strain. As a result, the fatigue resistance of the solder joint is increased. Combination of dopants, such as indium and cadmium, in combined amounts of less than 0.5 weight % are especially effective in increasing the fatigue resistance of the lead-tin eutectic solder.
